I said there was correlation, not causation. There may be a study out there but I don't have the time to dig for it.

Did this come from the same study observed the town in MA that determined when on a diet of animal fats and meat, fruit, vegetables, eggs, bread, TV dinners, ice cream, chocolate and so on, they determined that fat consumption was directly correlated to obesity and heart disease and thus the government mandated food pyramid was created? Poor science and lack of variable control inevitably lead to garbage like this.
